  • How to specify streams by pid with ffmpeg, If the value of pid is duplicated ?

    22 novembre 2019, par Bo Wang

    I have a nice m2ts file and I would like to demux specific audio streams from it. Of important, this specification is needed to use PID as identifier.
    The exemplified m2ts file has 7 audio streams, which is detected by eac3to and shown below

    eac3to.exe F:\xxx 1)
    
M2TS, 1 video track, 7 audio tracks, 5 subtitle tracks, 1:40:03
    
1: Chapters, 34 chapters
    
2: h265/HEVC, 2160p24 /1.001 (16:9), 10 bits
    
3: TrueHD/AC3 (Atmos), English, 7.1 channels, 48kHz, dialnorm: -28dB
    
   (embedded: AC3, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB)
    
4: E-AC3, English, 7.1 channels, 1024kbps, 48kHz, dialnorm: -28dB
    
   (core: AC3, 5.1 channels, 576kbps, 48kHz, dialnorm: -28dB)
    
5: AC3, English, 5.1 channels, 640kbps, 48kHz, dialnorm: -27dB
    
6: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
7: AC3, English, 2.0 channels, 320kbps, 48kHz, dialnorm: -27dB
    
8: AC3, Chinese, 2.0 channels, 448kbps, 48kHz
    
9: AC3, Chinese, 5.1 channels, 384kbps, 48kHz, 300ms

    However, if I run
    ffmpeg.exe -hide_banner -i "F:\xxx\BDMV\STREAM\00055.m2ts", ffmpeg shows an additional audio stream as it recognizes the embedded 5.1 AC3 stream inside the 7.1 TrueHD audio stream, as independent :

  • How to reinsert edited metadata stream information from the FFMETADATAFILE file ? [closed]

    6 septembre 2024, par SENYCH

    I'm working on simplifying and speeding up the process of editing video metadata for user convenience. I've successfully edited metadata streams using console commands, such as :

    


    ffmpeg -i INPUT.mp4 -map 0 -metadata:s:0 "handler_name=An other video" -metadata:s:1 "handler_name=An other audio recording in russian" -metadata:s:2 "handler_name=An other audio recording in english" -metadata:s:3 "handler_name=An other audio recording in japanese" -c copy OUTPUT.mp4


    


    However, I'd like to accomplish this through a ffmetadata file. Here's the approach I've taken :

    


    ffmpeg -t 0 -i INPUT.mp4 -map 0 -c copy -f ffmetadata ffmetadata.txt -hide_banner


    


    Original ffmetadata.txt is :

    


    ;FFMETADATA1
major_brand=isom
minor_version=512
compatible_brands=isomiso2avc1mp41
encoder=Lavf61.5.101
[STREAM]
language=und
handler_name=The best video
vendor_id=[0][0][0][0]
[STREAM]
language=rus
handler_name=The best russian language
vendor_id=[0][0][0][0]
[STREAM]
language=eng
handler_name=The best english language
vendor_id=[0][0][0][0]
[STREAM]
language=jpn
handler_name=The best japanese language
vendor_id=[0][0][0][0]


    


    Edit the ffmetadata.txt file to update the handler_name values :

    


    ;FFMETADATA1
major_brand=isom
minor_version=512
compatible_brands=isomiso2avc1mp41
encoder=Lavf61.5.101
[STREAM]
language=und
handler_name=An other video
vendor_id=[0][0][0][0]
[STREAM]
language=rus
handler_name=An other audio recording in russian
vendor_id=[0][0][0][0]
[STREAM]
language=eng
handler_name=An other audio recording in english
vendor_id=[0][0][0][0]
[STREAM]
language=jpn
handler_name=An other audio recording in japanese
vendor_id=[0][0][0][0]


    


    Attempt to apply the updated metadata from ffmetadata2.txt :

    


    C:\Users\Alexander\Videos>ffmpeg -i INPUT.mp4 -i ffmetadata2.txt -map 0:v -map 0:a -map_metadata 1 -c copy OUTPUT2.mp4 -hide_banner


    


    Despite these steps, I've noticed that only the global metadata is updated, while the metadata for each stream remains unchanged. The console output shows that metadata for each stream is not updated as expected.

    


    What am I missing ? How can I ensure that the stream-specific metadata is also updated correctly when using a ffmetadata file ?

    


    Additional Information :

    


      

    • FFmpeg version : 2024-08-26-git-98610fe95f-full_build

      • 


    • The ffmetadata file format and the approach I've used should be correct according to the FFmpeg documentation.

      • 


    


    I would greatly appreciate any recommendations or suggestions on how to solve this problem !

    


    I found a bad solution for my problem, but it still isn't ideal as it requires specifying -map_metadata:s:N 1:s:N for each stream individually, which is quite cumbersome. Is there a way to simplify this process and avoid having to set metadata for each stream separately ?

    


    The command I’m using is :

    


    C:\Users\Alexander\Videos>ffmpeg -i INPUT.mp4 -i ffmetadata2.txt -map 0 -map_metadata:s:0 1:s:0 -map_metadata:s:1 1:s:1 -map_metadata:s:2 1:s:2 -map_metadata:s:3 1:s:3 -c copy OUTPUT2.mp4 -hide_banner


    


    This works, but having to specify -map_metadata:s:N for each stream creates extra work, especially as the number of streams increases. Is there a more efficient way to handle this ?
