ffmpeg avi fileopen failed with error Libertytown, Maryland

I thought virtual dub would be good for a one run, capture into a filtered finalized avi. Also see the Stream specifiers chapter. The entry filenames in the segment list are set by default to the basename of the corresponding segment files. In fact this is the first video I made with this camera that ffmpeg can't read so I wasn't aware of this problem.

segment_time_metadata If set to 1, every packet will contain the lavf.concat.start_time and the lavf.concat.duration packet metadata values which are the start_time and the duration of the respective file segments in the To do so, reopen output AVFormatContext (in case of API usage) or restart ffmpeg instance, cyclically changing tables_version value: ffmpeg -i source1.ts -codec copy -f mpegts -tables_version 0 udp:// ffmpeg -i share|improve this answer answered Jan 22 '15 at 12:47 Tim Long 346411 add a comment| up vote 0 down vote Just change your code from this: VideoCapture capture("guitarplaying.avi"); to this: CvCapture Yes.

If this option is not specified, the default adapter is used. This allows dumping sdp information when at least one output isn’t an rtp stream. (Requires at least one of the output formats to be rtp). -discard (input) Allows discarding specific streams It's fixed now (thanks, Pete!), but I had to fix VirtualDub too because it was crashing trying to Direct-stream those files. (VirtualDub was using a fixed 64K buffer to hold the its nothing but an mp4.

If the form "%d0Nd" is used, the string representing the number in each filename is 0-padded and N is the total number of 0-padded digits representing the number. The size of the output file is slightly more than the requested file size. -ss position (input/output) When used as an input option (before -i), seeks in this input file to Note that Windows Media Audio (wma) and Windows Media Video (wmv) use this muxer too. 4.2.1 Options It accepts the following options: packet_size Set the muxer packet size. VBR audio does not work really nicely -- it breaks compatibility with several parsers.

It makes ffmpeg omit the decoding and encoding step for the specified stream, so it does only demuxing and muxing. pattern_type accepts one of the following values. The syntax and meaning of the pattern is specified by the option pattern_type. For example, to set the stream 0 PID to 33 and the stream 1 PID to 36 for an output mpegts file: ffmpeg -i infile -streamid 0:33 -streamid 1:36 out.ts -bsf[:stream_specifier]

relative index: The 'idx1' chunk is supposed to point to data chunks using relative offsets within the LIST 'movi' chunk; however, some AVI files have absolute file offsets here instead. What could be causing this? By default, FFmpeg will run on the first device of the first platform. The output filename specifies the playlist filename.

vdpau Use VDPAU (Video Decode and Presentation API for Unix) hardware acceleration. This file can be useful for bug reports. As Macmade suggested, AVI is merely a container which can house different audio, video, or even closed caption codecs. Enabling aggressive recovery mode. [!] AVI: Keyframe flag reconstruction was not specified in open options and the video stream is not a known keyframe-only type.

The option -formats of the ff* tools will display the list of enabled demuxers. RIFF files consist of a series of chunks, each prefixed by a four-character chunk ID and a four-byte length. p.s.

One said it was due to bad frames at random points throughout the file and it fixed the files by skipping those frames, it still did not work after.Is there something The specified metadata will be set for each file packet. muxrate number Set a constant muxrate (default VBR). things are clicking into place in my brain now :-) Many thanks for the intelligence within VirtualDub.

Out point is exclusive, which means that the demuxer will not output packets with a decoding timestamp greater or equal to Out point. Your dropped frames make frame accuracy even more difficult. Forces hls_list_size to 0; the playlist can only be appended to. again, when i capture from the regular tv tuner through the vcr, the lines are all merged and synced.

All files must have the same streams (same codecs, same time base, etc.). These default mappings are disabled by creating any mapping of the relevant type. For the situation where multiple output files exist, a streamid may be reassigned to a different value. With the sample code for VideoCapture, my visual studio program failed to open any video file.

So why avi video cannot be opened? In an input metadata specifier, the first matching stream is copied from. Setting it to different and sufficiently large values ensures that the produced ogg files can be safely chained. 4.23 segment, stream_segment, ssegment Basic stream segmenter. Google for it.

Yes, Any Video converter Professional and Any Video Converter Ultimate can do a good job on DVD conversion. I have other, smaller files that do not have this problem. It is disabled by default. This isn't too important for playback from a hard disk, and modern players are very good at handling non-interleaved or badly interleaved files, but properinterleaving is critical for proper playback in
